Your videos aren't boring IMO, youre pretty entertaining actually. I feel like you could benefit from more cuts though in this video, I also feel like your mic is a bit low volume. The thumbnail is good but I feel like It could be improved by taking out your character or making it stand out from the background some more and change the expression to something more of disgust.
You could also maybe change the title to something more like "These games made me rethink my life" or for something similar "I REGRET playing these games"
